Pirelli hasten changes after Ecclestone criticism

2 Comments

Pirelli will implement changes to their 2013-specification changes sooner than planned following criticism for Formula One boss Bernie Ecclestone.

Formula One’s official tire supplier announced on Tuesday it will bring revised compounds in time for the Canadian Grand Prix instead of the British Grand Prix, as they had previously indicated.

The changes to the tires aim to prevent drivers from needing to make four pit stops per race, as occurred in Spain, and to address the delamination problems that have been seen.

“Our aim is to provide the teams with a new range which mixes the stability of the 2012 tyres and the performance of the current ones,” said Pirelli motorsport director Paul Hembery.

“As a company, we have always moved quickly to make improvements where we see them to be necessary. After evaluating data from the first few races this year, we’ve decided to introduce a further evolution as it became clear at the Spanish Grand Prix that the number of pit stops was too high.”

“We’ve also taken this step to avoid the delaminations that were caused by track debris,” Hembery added.

“It’s important to point out that these delaminations, which occur when the tread comes off, do not compromise the safety of the tyres as the core structure of the tyre is not affected in any way, helping drivers to complete the lap and to change the damaged tyres safely. These delaminations were due to damage from debris that overheated the tread.”

Felipe Massa suffered two tire failures during the race in Bahrain, Lewis Hamilton had a tire problem during practice for the same race, and Paul di Resta had a similar failure during practice in Spain.

Ecclestone criticised Pirelli following the Spanish Grand Prix, which saw drivers make a total of 77 pit stops.

“The tyres are wrong, not what we intended when we asked Pirelli to produce something which did a half race,” Ecclestone told the Daily Express.

Day 3 of pre-season testing at Homestead-Miami Speedway saw the Pro Mazda Championship Presented by Cooper Tires and the Cooper Tires USF2000 Championship Powered by Mazda continue testing for the second day in a row, with each series completing three sessions on what was their final day of running.

Quick reports on both series are below.

Pro Mazda: Cunha Surges to the Front

While Saturday saw Pro Mazda newcomers like Oliver Askew, Parker Thompson, and Rinus VeeKey lead the way, Sunday saw a pair of second-year Pro Mazda drivers take their turns at the top of the speed charts. In the combined results, Juncos Racing’s Carlos Cunha turned the fastest lap of the final session, also good enough to be the outright fastest lap of the weekend, taking advantage of a fresh set of Cooper Tires to do so.

“I’m really happy, Juncos Racing is an amazing team,” Cunha said of the team’s performance. “On track, we are always improving, never going backwards and that’s very good. We have tested a lot but we still need to learn a lot about the car, though we are almost to a perfect setup. The team has given me everything I need to be comfortable inside the car, to know what the car needs, and to know what I need to be a better driver. We have time to improve and we are moving forward quickly.”

Fellow sophomore driver Sting Ray Robb, now with Team Pelfrey, was right behind Cunha in second.

Combined results across both Saturday and Sunday can be found here.

USF2000: Kirkwood, Cape Motorsports Stay On Top of Deep USF2000 Field

New Cape Motorsports driver Kyle Kirkwood, who topped Session 2 on Saturday, stayed on top of the combined speed charts across the weekend on the strength of his best lap from Session 3 of the weekend on Saturday.

Pabst Racing’s Rasmus Lindh was right behind Kirkwood, on the strength of his quick lap from Session 1.

However, Sunday’s running saw a different driver assert his authority, with Kaylen Frederick, Lindh’s teammate at Pabst, turning the fastest lap during the final session.

Frederick ended up fourth in the combined results, which can be viewed here.

The Indy Lights Presented by Cooper Tires will take to the Homestead-Miami road course on Monday for the final day of testing for the Mazda Road to Indy.
